The first one is correct. You pass a reference to the element itself, so
you can query the value and the id from the element.

Also note, that "orient" is not a valid attribute! This is only specific
to Firefox and not allowed in HTML5. If you want to get a slider which
is vertical and uses valid HTML you need to use CSS.

Also see:
<https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/range>

Minimal example:

<!DOCTYPE html>
<html>
<head>
<title>Example for onChange</title>
<style>
.slider-wrapper {
  display: inline-block;
  width: 20px;
  height: 150px;
  padding: 0;
}
.vertical-slider {
  width: 150px;
  height: 20px;
  margin: 0;
  transform-origin: 75px 75px;
  transform: rotate(-90deg);
}
</style>
</head>
<body>
<div class="slider-wrapper">
<input type="range" class="vertical-slider" id="korgvol1"
       min="0" max="127"
       onChange="korgvol(this)"
/>
</div>
<script>
function korgvol(e)
{
    alert('ID: ' + e.id + ' / Selected value: ' + e.value);
}
</script>
</body>
</html>
